Abstract
An electromagnetic actuator includes a pair of core assemblies and a spacer. An armature is provided between the pair of core assemblies. The spacer is molded to be integral with a coil provided in electromagnets of the core assemblies. The spacer is located between the electromagnets. A relative position of the pair of electromagnets with respect to each other can be determined by the size of the spacer. A space that allows the armature to reciprocate is securely defined by the spacer located between the core assemblies.
Claims9
An electromagnetic actuator comprising:
- an armature that reciprocates along an axis;
- a pair of electromagnets, each having a coil, the pair of electromagnets provided along the axis and on opposite sides of the armature;
- and
- a spacer formed by molding to be integral with the coil and located between the pair of electromagnets, the spacer secures a space for the armature to reciprocate along the axis.
